Mornsun PV15/PV40-29Bxx series DC/DC converters for PV systems

The PV15/PV40-29Bxx series 15 and 40 W DC/DC converters provide 200–1500 VDC input voltage and high isolation voltage of 4000 VAC. Input voltage from 200 to 1500 VDC allows for longer strings to be used in the PV system.

A PV system converts the sun’s radiation into usable electricity and also powers itself. The sunlight’s intensity is often not stable, so voltage to the control system also varies. This may lead to frequent system restarts.

The series is designed with input undervoltage protection, which can protect system stability from these frequent restarts. It also features reverse-voltage, output short-circuit, overcurrent and overvoltage protection.

With a wide operating temperature of -40 to +70°C, 4 kV isolation voltage and high efficiency, the series is suitable for applications such as photovoltaic combiners, photovoltaic inverters, high-voltage switching, etc. It meets the EN62109 standard and suits high-altitude applications (up to 5000 m), ensuring system safety.

The product has been released by Mornsun and is distributed in ANZ by DLPC and in Victoria by Fairmont Marketing.
